I'm trying to recreate the Gameboy BIOS in Construct just for kicks and so far, I've managed to quickly get it mostly working.

I'm basically having the Nintendo logo scroll down from the top of the screen via the bullet behavior, and then stop once its Y position reaches a certain point. From there it's supposed to play a sound, which is where I've been having trouble:

Instead of playing only once, it continues to loop for the duration of time I've specified the game to wait before moving to the next layout.
